Compute the minimal tolerance of the parametric domain i.e. ToleranceMin =Boundary.Length()* MINIMAL_UNIT_LINEAR_TOLERANCE e.g. for a curve of 1m with a parametric space define between [0, 1], the parametric tolerance is 0.01 This is a minimal value that has to be replace with a more accurate value when its possible
